SECTIONAL HULL STRUCTURE FOR HOUSE-BOATS OR'THE LIKE Application filed February 14, 1931'. Serial No. 515,846.. 3

This invention relates to watercrafiaand has particular reference to van improved sectional structure of a hull or buoyancy element for use in connection with houseboats or for other similar purposes, the same being in the nature of an improvement upon the hull structure set forth in my prior United States Letters Patent No. 1,7 88,264, granted January 6, 1931.

In addition to accomplishing generally the objects set forth in the prior patent above referred to, the present invention aims to provide a hull structure or buoyancy element in which more individual compartments are afforded for the obvious purpose of increasing the safety factor. n

The invention further aims to provide a sectional. hull structure, by virtue of which the'renewal of the sections or repairs thereto rein event of damage, may beaccomplished with greater facility. g 7

As a still further object, the invention contemplates the provisionof a rigid keel memher which is continuous throughout. the height and length of the hull and to the opposite sides of which the hollow water-tight hullsections are secured in such a manner as to relieve said hull sections of all strains,

and stresses except those imparted thereto 59 by the water pressure. 4 Y ,The invention further embodies in connection with a continuous rigid keel; member, continuous rigid gunwale strips secured at the opposite ends to each" other and to the opposite ends of the keel member and spaced apart between said secured endsto receive between said keel member andthe gunwale strips, the hollow. water-tight hull sections, together with means for securing said hull sections in assembled relation with respect to the keel member and gunwale strips, and further. to afford-means whereby said hull sections/may be independently removed and replaced. I I As a still further object, the invention resides in the provision ofv hollow water-tight hull sections which are fashioned from a pair of sheets of material secured together in water-tight r'elation,,whereby said hull sec- 9 tions maybe economically produced.

With the above recited and other objects in view, reference is had to the following description and accompanying drawings, in which there is exhibited one example or embodiment ofthe invention, while the claims define the actual scope ofthe same.

In the drawings: I

Figure 2 is a side elevation thereof.

Figure 3 is a transverse sectional lview taken approximately on the line 3-3 of F igure 1 and at a point between adjacenthull 1 sections. 7 y a I Figure 4 is asimilar view taken approximately on the line 4-4 of Figure 1, in a plane intersecting the hull sections. 7 Figure 5 is a fragmentary longitudinal sectional view'taken approximately on the line 5+5 of Figure 1, and illustrating one of the hull sections removed. 7 '3 Figure 6 is a perspective view of one of the hull sections removed. 1

Figure is a similar view of the inner part ofone of the hull sections prior to the assem-- bly of the outer part therewith.

Referring to the drawings by characters of reference,the hull construction includes a rigid keel member A which is continuous throughout the length and height of thehull and which maybe either in the nature of a flat plate, as illustrated, or equivalently formed and properly shaped to follow the profile configuration of the hull. The construction further includes hollow water-tight bow or stern and intermediate sections designated generally by the reference characters B and C, it being understood that the said bow or stern sections B are substantially identical in 'construction. The hull sections B and C are disposed on opposite sides of the keel member A and are removably secured thereto. In addition to the keel member and hull sections, the construction further includes a; pair of continuous rigid gunwale strips designated generally by the reference character D, the opposite ends of which strips are secured to each other and the opposite ends of the keel member and are spaced apart between said secured ends and located adjacent the upper portion of the hull and extend thereabove to afford means for securing the hull sections in assembled relation, and to further function as a deck supporting means.

The intermediate hull sections C include an inner part designated generally by the reference character 10 and an outer part designated generally by the reference char acter 11, each of which is fashioned from a single sheet of material, the inner part being formed to provide an inner vertical side wall 12 having integral angularly disposed outwardly projecting vertical end walls 13; The inner side wall 12 is formed at its upper and lower edges with outwardly projecting horizontal flanges 14 and 15, while the end walls 13 are formed at the free upper, lower and outer edges with longitudinally projecting continuous flanges 16, 17 and 18. The outer part 11 of each hull section is formed with an outer side wall 19 and integral angularly dis- C, A ia posed inwardly extending top and bottom walls 20 and 21. The free inner edge of the top wall 20 isprovided with an upwardly projecting longitudinally extending flange 22, while the free inner edge of the bottom wall 21 is'provided with a downwardly directed longitudinally extending flange 23. The flanges 22 and 23are preferably formed integral and are disposed in the same vertical plane'with the inner side wall 12 of the inner part 10 when the sections are assembled. The parts 10 and 11 are secured together in water-tight relation in any suitable manner, such as by rivets 24, which extend through the marginal edges of the'walls 19, 20 and 21 of the outer part 11 and the flanges 1 1, 15, 16 and 17 of the inner part 10.

The end hull sections B which constitute either the bow or stern sections are substantially identical with the intermediate sections C, with the exception of being shaped to reduce head resistance or drag, and this is accomplished by curving or otherwise forming the outer side wall 1964 so that it converges with respect to the inner side wall and correspondingly shaping the top and bottom walls. The flanges 22' and 23 of the hull sections are designed to flatly contact with the side faces of the keel member A and are designed to receive therethrough suitable securing means, such as. the bolts 25, by virtue of which said sections may be independently secured to the keel member A for separate removal from and application thereto. The hull sections are further provided with outwardly projecting horizontal flanges 26 which extend longitudinally thereof and are spaced in a plane below the top walls 20 of the sec tions to underlie and bear against the under surfaces of the gunwale strips 1) for removable securement thereto in any desired manner, such as by the bolts 27. t will also be observed that the upper portions of the hull sections are snugly fitted between the inner sides of the gunwale strips and the sides of the keel member A, to further insure against lateral movement of the sections with respect to the keel member. As will be observed, the extremities of the gunwale strips D are secured to each other and to the keel member and end sections B by any suitable means, such as the bolts 28, which may be removed when an end section is to be displaced.

From the construction set forth, it is apparentthat a buoyancy'e'lement or hull struc ture has been devised, in which the hull sections are'assembled in such a manner as to facilitate the independent removal and application thereof, whereby they may be renewed or repaired economically in event of damage. It will be further observed that due to the manner of assembly of the various elements, the hull sections'a're relieved of all longitudinal or other strains by the keel member and gunwale strips and may be constructed of a material of only the proper gauge to withstand the water pressure. It will also further be observed that the hull sections 'may be cheaply constructed so that the hull structure in its entirety may be economically produced.

lVhile there has been illustrated and described a single and preferred embodiment of the invention, it is to be clearly understood that no limitation is necessarily intended to the precise structural details, but that variations and modifications t'vhich properly fall within the scope of the claims may be resorted to when found expedient.
